Looks amazing. Awesome build. What are the plans for the motor? Even near stock it should go pretty well.

I think so too. Awesome car. If I ever build an older car it will be just like this. Modern motor, etc.
My friend is building a Shelby Cobra replica with a LS6 in it.

First look around. This is a really neat project. Like others I like the old exterior with modern underpinnings. I hope you give it a spin around the autocross courses. This can really keep the flame alive after you tighten the "last" bolt. Lenny

Read through the posts which raised a question...
Do you do upholstery work as a profession? Or are you a medical doctor?
Super nice job on the car and quick progress.
What are using for an engine controller? Lenny

What are using for an engine controller? Lenny M.D. I just happen to know how to fix old Fiero seats. (did some on an 82 Vette I restored). As far as the engine controller, Vince Lung is helping me with that and a few other things. We are not there yet........any suggestions?

I always wondered if being MD would preclude one from getting grease under the finger nails. I'm guessing there's a fine line in that thought.
In retro-injections systems, I've used a first gen Accel sequential DFI, a first gen FAST controller, and just recently a Accel Gen7 DFI. Like computers, each newer version seems to be easier to use.
Accel recently placed an indefinite hold on their Gen 8 program. From my reads, the latest FAST seems to be favored over the Gen 7. BigStuff has big supporters and big opponents. On forums, it's hard for me to tell what to believe.
If I were to build a chev LS engine, I think I'd use a factory contoller. Not completely sure why, but assume that with the factory development exercise comes a better solution. Maybe Vince can chime in. Are you using the factory controller on your dual turbo C5? Can you tell us about the tuning experience?
Merry Christmas everyone.
Lenny

I have a gen 7 and after spending some time with Eli at Accel I have come to enjoy it. If you would like I can show you the in's and outs. One of the FAST groups had a play and plug with the fast, the claim is 30 minutes and your running.. Sounds very interesting. Here's the link....http://www.whiteracing.com/PnPInstall.html Merry Xmas

First,the docs car will be running (at least initially) a custom tuned OEM 03 Cobra computer as we are not looking at anything more extravagant than perhaps pulley down and exh work. My car is still running a OE computer on a 2BAR custom OS,which is nice for tuning my application(good resolution in the MAP while in boost) as well as several other nice features. I DO however switch back to standard closed loop MAF setup for emissions purposes being careful not to get too deeply into boost.If the car were race only I would consider FAST or some other stand alone Controller but I like the integration with the factory setup and can live with the limitations my setup currently has.Tuning in open loop with datalogging is relatively straightforward,and most of the time(unless your laptop dies) the car responds well to the changes. I hope everyone has a safe,enjoyable xmas holiday,and cant wait to see ya all at the track next year !!!! ;D

I'd guess that factory controllers are limited when controlling NO2 or other add on devices ... What other limitation do you encounter with the factory controller?
Can a wideband O2 sensor be easily tied in with tuning a factory controller?
What software did you use to modify the factory controller? I've read about different packages but not heard first hand experiences. Please enlighten us. Lenny

Is it the stock Cobra one that doesn't use a return line? I have a 99 Cobra. It never worked well at partial throttle with a Paxton blower on it. I finally jerked the whole thing off and went back to the stock configuration. The last thing I changed back was the boosted fuel pump, and that turned out to have been the problem the whole time. Having 500hp was nice, but the car was annoyingly erratic when you weren't racing it.

I've read about different packages but not heard first hand experiences. Please enlighten us. Lenny I will quickly answer yours and Richards questions concerning this car and start a separate post on tuning/adj done to my car so as not to clog up the Docs post ! On his car,currently no plans to run 2-step/NOS/ multiple tune reflash just a nicely tuned good running street driven car.As for the fuel system,we have had good luck with a properly setup returnless system in the vettes(See Snowmans dyno sheet for reference !!!) We will be running a similar setup in the Docs car with custom Pump/lines as we are using the 69 Tank. If we find an issue under boost or any indications of lean spike/loss/lack of fuel we can easily(well relatively) go to a boost ref return type setup,just need different(FAST) rails/return line and regulator. I dont anticipate any problems as I have several fellow racers running between 500-750 to the wheel on Mustang/Cobra returnless setups and that is above the current project goal HP wise. I will keep you posted as we go,and will start another thread on the tuning if you have additional questions.
